description
Across the Logan Zone, wind slabs are forming on weak preexisting snow. Dangerous wind slab avalanche conditions exist in exposed terrain at upper and mid elevations. The danger could rise further tonight as the next wave of Pacific storminess impacts the area, with more snow and drifting from strong west winds. Human triggered wind slab avalanches are likely on drifted slopes.
